PCD232A控制單元，英文ControlUnit (CU)，是PU部件之一，有時(shí)也安裝與CPU外部，其基本功能是從內(nèi)存取指令分析指令和執(zhí)行指令。
控制單元是實(shí)現(xiàn)一種或多種控制規(guī)律的控制儀表或控制部件。如: 多路傳輸控制單元、代理設(shè)置控制單元
種類

PCD232A

PCD232A無論哪一個(gè)種類的控制單元，原理均為通過控制單元發(fā)出的控制信號(hào)對(duì)CPU各部分加以控制，控制單元大體可以分為以下兩類。
微程序式，由微程序讀取和發(fā)出控制信號(hào)。通過被稱為微型定序器的簡(jiǎn)單數(shù)字通路(微型電腦)對(duì)微程序加以執(zhí)行。硬件型控制單元，由數(shù)字通路直接發(fā)出控制信號(hào)。由于集成電路的規(guī)模化及設(shè)計(jì)技術(shù)的進(jìn)步，此種控制單元已成為可能，功能
PCD232A它根據(jù)用戶預(yù)先編好的程席，依次從存儲(chǔ)器中取出各條指今，放在指今寄存器R中，通過指今譯碼(分析)確定應(yīng)亥進(jìn)行什么操作，然后通過操作控制0C，按確定的時(shí)席，向相應(yīng)的部件發(fā)出微操作控制信號(hào)。操作控制器OC中主要包括節(jié)拍脈沖發(fā)生器、控制矩陣、時(shí)鐘脈沖發(fā)生器、復(fù)位電路和啟停電路等控制邏輯

The PCD232A control unit, ControlUnit (CU), is one of the PU components, sometimes also installed outside the CPU, its basic function is to access instructions from the inside to analyze instructions and execute instructions.
A control unit is a control instrument or control component that realizes one or more control laws. For example, multiple transmission control unit and proxy setting control unit
species
PCD232A No matter which kind of control unit, the principle is to control all parts of the CPU through the control signal issued by the control unit, the control unit can be broadly divided into the following two categories.
Microprogram type, which reads and sends control signals by microprogram. The microprogram is executed through a simple digital path called a microsequencer (microcomputer). Hardware-type control unit, which sends control signal directly by digital path. Due to the scale of integrated circuits and the progress of design technology, such control units have become possible and functional
PCD232A according to the user’s pre-programmed program, take out each finger from the memory in turn, put it in the finger register R, determine what operation should be carried out by the finger decoding (analysis), and then through the operation control 0C, according to the determined time, send a microoperation control signal to the corresponding component. The operation controller OC mainly includes the control logic of beat pulse generator, control matrix, clock pulse generator, reset circuit and power off circuit
